"Faces with Social Darwinism"

Pamela Druckerman and Rachael Snyder's book tells the story of 60 years of transplant surgery by Adam Sirbu and Ben Barres of Case Western Reserve University, who treated hundreds of dying patients with only a master's degree in genetics and a high tolerance for pain.

Emma Graham-Harrison:

The most ambitious documentary I have seen about the present day, although some of the conversations are the same as those shown in other documentaries, about how humans coexist in this world, and are completely aware of just how good it is we are.

"No Easy Day: The Firsthand Account of the Mission That Killed Osama bin Laden"

Jason Binn's magazine empire expanded its website Buzzfeed into a portal for a gaggle of news and business properties. The publication did some ground-breaking journalism, but fell away from it after he lost money.

At the time of his death, he was working on "No Easy Day," which retells the raid on bin Laden's compound in Abbottabad, Pakistan.

I spoke to Joe Carnahan, the director of the movie:

"The CIA asked me to rewrite it twice and tell them it was the Navy SEALS, but I said no. So there's a surprise in there for both sides. I feel bad because I hate the CIA, but no one can take credit for the action."

What you need to know about the Coronavirus

Sara Seager, an atmospheric sciences professor at the Massachusetts Institute of Technology, warned that a strain of the coronavirus (which has killed 49 people in Saudi Arabia, Qatar and Jordan) could evolve into a mutated form that would pose a greater threat, according to Scientific American.

Prof. Seager worried that the strain of coronavirus presents a "risk to health." In a press release, she said that every year about 400,000 people get SARS.
